Data sheet

Formulation
Lyophilized from a 0.2um filtered concentrated (1mg/ml) solution in PBS, pH 7.4.
Solubility
It is recommended to reconstitute the lyophilized Interleukin-4 in sterile 18M-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.
Purity
Greater than 97.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE.
Description
Interleukin-4 Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 130 amino acids and having a molecular mass of 15kDa. The IL-4 is purified by proprietary chromatographic techniques.
